Letters Patent No. 98,655, dated Januar/y 4, 1870.

IMPROVE!) LUBRICATOR.

lill

. il To all whom it 'may concern:

Beit known that I, ROYAL S. HILDRETH, of South Adams, in the countyBerkshire, and State of' Massachusetts, have invented a new and usefulImprovement in Lnbricators; and I do .hereby declare that the followingis a full, clear, and exact description thereof, which will enableothersskilled in the art to make and use the same, reference being hadto the accompanying drawings, forming part of this specification.

The object of this invention is to furnish Va simple and cheap means foroiling or lubricating journals in all situations; and consists in theuse of a spring within the oil-cup, in connection with an oiliug-wire,so arranged that the wire shall be at all times pressed against thejournal, in whatever position the oilcup may be placed, as will behereinafter more fully described.

The accompanying drawing represents a vertical section of thelubricator, as when in use, in 'a vertical position, the journal andjournal-box being shown in dottd lines.

Similar letters of reference indicate corresponding parts.

A is the oil-cup, which is made of glass, or of other suitable material,with a metallic collar, B, cemented to the neck, on which collar isfitted a tubular screwcap, C, as seen in the drawing:

I) is an oiling-wire, which passes loosely through the tubular cap, tothe innerI end of'wbich there is attached a spiral spring, E.

The spring bears upon the bottom of the cup, and the outer endl oftbe'vyire D bears on the journal.

Tbetube of the cap G is screwed into the box-cap, so that the oil, whichflows through the tubeA around the wire, will be conducted by the wireto the journal. The same result is produced when the cup is placed in ahorizontal instead of a vertical position, or in any other position, solong asthe oil in the cup rises above the end of the wire.

It will be readily seen that the wire and spring may be so adjustedthatthe end of the wire will press constantly against an uneven surface, as,for instance, for oiling a cam; but I design it more especially forjournals of upright sbafts,.and for use generally where ordinarylubrication cannotl be applied, or Where they are only partiallyeiective.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The combinationof oil-cup A, collar B, cap C, spring E, and wire I), all arrangedV andfitted together as and for the purpose specied.

R. S. HILDRE'IH.
